Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
Answer:
Eva has 24 pins
Step-by-step explanation:
D = 34 + E
E + D = 82
34 + E + E = 82
2E = 48
E = 24
D = 24 + 34
D = 58
Answer:
hii there
The correct answer is option ( B )
Step-by-step explanation:
hope it helps
have a nice day
4y + x = 4 . . . . . . . (1)
2y - x = 8 . . . . . . . (2)
(1) + (2) => 6y = 12
y = 12/6 = 2
From (2), 2(2) - x = 8
4 - x = 8
x = 4 - 8 = -4
Therefore solution is (-4, 2) and lies on both lines.
